The Age in Australia reports that the country's tech research agency has won a lawsuit over Wi-Fi patents against Buffalo Technology in a US court: The Age says that CSIRO (Commonwealth Scientific and Industrial Research Organisation) prevailed in a suit over patent 5,487,069 filed Nov. 23, 1993, and awarded Jan. 23, 1996, that covers fundamental aspects of WLAN communications. The patent describes multipath transmission of data at frequencies higher than 10 GHz, but the agency says a court in the eastern district of Texas found for CSIRO. They were asking for royalties from Buffalo; the case was filed in Feb. 2005. I've uploaded the court opinion and memorandum released Monday.
CSIRO intends to pursue royalties from all companies making Wi-Fi and other products, which could easily include WiMax and Bluetooth devices.
Intel, Dell, Microsoft, HP, and NetGear are engaged in two lawsuits to get the patent invalidated. CSIRO says that as a foreign government body, it cannot be sued. But, apparently, it can sue and collect patent royalties. Fascinating.
